2 Product Description
2.1 Room unit
The objective of the room unit is to display the information provided by the installed sensors and make
it possible for the user to enter desired settings. The room unit is equipped with 2 internal sensors;
Temperature and humidity sensor, which register the temperature and humidity in the location of the
installed room unit. It is possible to connect 2 extra sensors to the internal connection block.
Up to 10 room units can be active simultaneously.
Note:
The installed room units can only be regulated one by one. It is not possible to perform settings on
two or more controls simultaneously!
In order for the room unit to function the control board needs to be installed and connected. See

3.2 Program overview
The program interface is separated in three levels.
• User level is intended to be used by any user of the system. It’s only possible to change a limited
number of parameters
• Service level is intended to be used by persons with some knowledge of the system. For example care
taker or similar
• Installation level is used for advanced setting and is intended for the installation personnel that do the
initial setup of the complete system.
3.2.1 Navigation
The room unit has two buttons and a knob.
• Menu selector (choose function and move in menus)
•Confirm(buttontoconfirm choice)
• Back (button to go back in menu level)
Items in the menu that lead to a sub menu level are marked with >>. Itemsthatleadtoamenuwith
changeable items are marked with>. Changeable Parameters and values in menus are marked with
underscore. When turning the knob the selected value is marked with inverted background colour. The
Confirm button will enable changes of value, this is indicated by flashing the inverted background colour
on and off.
After a value has been changed the change must be confirmed with the Confirm button. If the back button
is used the value will go back to previous. Inactivity for 1 min. is the same as selecting back button.
The display back light will be activated from any user input. The back light goes off after 1 min. of inactivity
except for the adjusting menu where the back light is always on
The password menu has a time out of 15 sec.
3.2.2 User menu
The control mode list shows activated selection. If only manual is chosen and a manual controller is
selected the controller mode menu is not shown
Manual controller setting menu has no time out.
The temperature icon is connected to the set point for the heater/cooler. If no heater/cooler controller is
activated the icon is connected to the first temperature controller for the fan. If there are no temperature
controllers in the system the temperature icon is not shown. The Alarm icon flashes in case of alarm and
an alarm message is shown; if more than one alarm is activated the messages alternate.
In the bottom of the display the actual operate mode is shown.
This can be:
•Auto
• Boost: 00:30 (remaining time counter, in this example the remaining boost time is 30 minutes)

3.3 Set up cases
Below set up cases describe some of the most common regulation examples. All the cases assume that the
room unit and control board have been installed and connected according to the installation instructions.
3.3.1 Pressure control with outdoor temperature
compensation
Youwouldlikethefantokeepaconstantpressureintheductanddecreasethesetductpressurewith
50 Pa in case the outdoor temperature drops to -10°C or lower. The user should be able to set the duct
pressure within a determined range.
It should also be possible to turn off the fan with an external potential free switch, for example a timer.
For this set up you need the following:
• One pressure sensor
• One Temperature sensor (PT1000)
• One potential free on/off switch, e.g. timer.
Do the installation according to below procedure:
1 Install pressure sensor and temperature
sensor
Install the pressure sensor in the ventilation duct
and the outdoor temperature sensor. Connect the
pressure sensor to the control board to IN 1 (pos.
B) and the temperature sensor to IN2 (pos. C).

13 Set point displacement/Setting
Set between which temperatures you want the pressure dis pla ce ment. Set Start for example to
0,0 °C and Stop to -10 °C.
Set the Displacement to -50 Pa.
Note:
This is only possible if the value in the set point range is adjusted to include the desired pressure
decrease value. E.g. a displacement of -50 Pa using 0–200 Pa sensor would have to increase the min.
value 20+50 = 70 Pa in order for the pressure set point to be able to decrease 50 Pa.

8 Sensor range
Select Sensor range and set the maximum airflow for the air speed sensor in l/s.
Note:
The range of the analogue air speed sensor is normally given in m/s written on the sensor label. You
have to calculate the l/s depending on the actual duct diameter where the sensor is situated. For
example a maximum air speed of 10 m/s in a 200 mm circular duct would give 314 l/s based on the
formula A x V x 1000, where A is the duct cross section area in m² and V is the air velocity in m/s.
Set if the sensor scale is linear, i.e. if an air velocity sensor is used, or exponential, in case a differenti
al
pressure sensor connected to a damper is being used (section 3.2.16). Default is Linear.

3.4 Set up of operation schedules
The week schedule is used if you want the fan to operate differently from how controller 1 is setup during a
specific time of the day, e.g. if you want
the system to be turned off during a certain time of the day or
go to a different set point, e.g. forced ventilation.
It is po ssible to set up to 14 tim e s
chedules for Controller 1. The settings in the week schedule overrides
the settings determined in the setup of the system or the set point made by the user.
Note:
Make sure time and date has bee
n set in the service menu.

3.4.1 Set up example
we will use the set up case based on above example “Pressure control with outdoor temperature
compensation” (section 3.3.1).
In this imagined example you want the week program to achieve the following result:
• Monday to Friday the system should go to maximum speed between 07:00–09:00
• Monday to Friday 09:00–18:00 the system should operate according to above setup case (section
3.3.1.) with the pressure set point determined by the user
• Monday to Friday the system should be turned off at 18:00
• During Saturday and Sunday 09:00–22:00 you want the fan to operate at 30% and be turned off at 22:00
Do the setup according to below procedure:
1Setup
Go to the service icon and select Setup
2 Time C ontrol
Choose Controllers and scroll down to Time Control.Byconfirming
you enter into the Schedule
setup menu.
3 Schedule 1
Start programming Schedule 1.
Set On 07:00 Mon-Fri, Off 09:00 Mon-Fri and Speed 100
%.
The fan will now work at 100% speed between 07:00 and 09:00 Monday to Friday regardless of what
has been set in the setup procedure for the system o
r chosen user set point.
4 Schedule 2
Go to Schedule 2.
Set On 18:00 Mon-Fri, Off 07:00 Mon-Fri and Speed Off %.
The Off period for the system is now started at 18:00 and stopped at 07:00 Monday to Friday. The
system will also be in Off mode Friday 18:00 to Monday 07:00 after this schedule has been programmed.
Since there is no active setting done in the schedule between 09:00–18:00 Monday to Friday the
system will operate according to setup parameters (section 3.3.1) and according to user set point
during this period.
Note:
The Off period needs to be determined with an On and Off time as well.
5 Schedule 3
Go to Schedule 3.
Set On 09:00 Sat-Sun, Off 22:00 Sat-Sun and Speed 30 %.
The system will operate at 30% speed 09:00–22:00 Saturday to Sunday. This is possible since this
time schedule was programmed after the activity determined by schedule 2. After 22:00 on Saturday
and Sunday the sy
stem will go back to Off mode since the activity determined in schedule 2 will again
become active.
